The Clutha District Council has issued an urgent boil water notice for some water schemes in the district as treatment plants struggle following the floods.
Clutha District Council service delivery group manager Jules Witt said a boil water notice was issued for consumers on the Richardson North Rural Water Scheme and in the Whitelea Rd area.
Mr Witt said several rivers were still dirty and the water treatment plants were struggling in the wake of flooding.
"As long as water has been fully boiled in an electric jug any bacteria and viruses should be destroyed."
Mr Witt said council was monitoring other water schemes to determine if boil water notices should also be implemented.
